Microchip PIC24FJ128GB106T-I/PT: A Comprehensive Technical Overview

The Microchip PIC24FJ128GB106T-I/PT stands as a prominent member of the PIC24F "General Purpose" 16-bit microcontroller family, engineered to deliver a powerful blend of performance, peripheral integration, and power efficiency. This device is particularly well-suited for a wide array of embedded applications, from industrial control and medical devices to advanced consumer electronics.

At the core of this microcontroller is a high-performance 16-bit modified Harvard architecture CPU capable of operating at speeds up to 16 MIPS. This processing power is driven by an internal 8 MHz oscillator, which can be leveraged with a Phase-Locked Loop (PLL) to achieve the device's maximum operating frequency, ensuring swift execution of complex control algorithms.

A defining feature of this MCU is its substantial and versatile memory configuration. It is equipped with 128 KB of self-programmable Flash memory and 8 KB of RAM. The Flash memory supports robust Run-Time Self-Programming (RTSP) and Enhanced In-Circuit Serial Programming (ICSP™), facilitating flexible field firmware updates. Furthermore, it boasts a 1 KB auxiliary Flash segment dedicated for use as a data EEPROM emulator, providing reliable non-volatile data storage without adding an external component.

The peripheral set integrated into this single chip is extensive and designed to minimize external part count. Key communication interfaces include:

Two UART modules with support for LIN-bus and IrDA®.

Two SPI™ modules for high-speed communication with peripherals.

Two I2C™ modules supporting both Standard and Fast Speed modes for connecting to a vast ecosystem of sensors and ICs.

A CAN 2.0b module, essential for robust automotive and industrial network applications.

For analog interfacing, the microcontroller incorporates a 10-bit, 500 ksps Analog-to-Digital Converter (ADC) with up to 16 channels, enabling precise measurement of multiple analog signals. It also features three operational amplifiers and three comparators on-chip, further enhancing its analog capabilities.

The device offers exceptional power management flexibility. It operates from a 1.8V to 3.6V range, making it compatible with both low-power and mainstream power supplies. It supports multiple power-saving modes, including Sleep, Idle, and Doze, allowing developers to finely tune the balance between performance and power consumption for battery-sensitive applications.

Housed in a 64-lead TQFP package, the PIC24FJ128GB106T-I/PT provides up to 52 general-purpose I/O pins, many of which are remappable, offering significant layout flexibility on the PCB. Its industrial temperature range (-40°C to +85°C) ensures reliable operation in harsh environmental conditions.

ICGOOODFIND: The PIC24FJ128GB106T-I/PT is a highly integrated and capable 16-bit microcontroller. Its combination of substantial memory, a rich suite of communication and analog peripherals, and advanced power management features makes it an exceptional choice for developers designing complex, connected, and power-conscious embedded systems.
